Where the Water Goes Can Decide the Deal
Part 1 covered detention pond rules, impact fees and zoning. Part 2 covers two issues that stall many Houston-area commercial sites: outfall access and roadway impact fees.
A site can look perfect on paper and still have nowhere legal to send its stormwater.

JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
When the Site Drains the Wrong Way
A property may slope away from the nearest storm sewer, or toward an outfall that will not accept it
Many jurisdictions now limit "new" drainage into systems that never received flow from the site
TxDOT Outfall Limits
TxDOT Houston District's drainage guidelines state that its drainage systems are not intended to provide drainage for new development
Where pumping is allowed, release limits and drain-time rules can still push a detention pond larger
Local Pumping Restrictions
Some cities restrict where a pumped detention pond can be located, such as distance from existing homes
Near neighborhoods, that can force a gravity design with more fill or storage
Roadway Impact Fees
Texas Local Government Code Chapter 395 allows impact fees for capital improvements, including roadway facilities, tied to "service units"
Roadway fees are commonly based on vehicle-miles, so high-trip uses like drive-thru restaurants can pay far more than a same-size warehouse

Outfall and Fee Rules in Texas, North Carolina and Florida
Texas
See the TxDOT Houston District Drainage Design Guidelines, Local Government Code Chapter 395, our TxDOT Houston drainage criteria post and Part 1.
North Carolina
Local development rules fall under G.S. Chapter 160D.
Florida
Stormwater discharge is reviewed through the FDEP Environmental Resource Permit program.
Frequently Asked Questions
Can I drain my site into a TxDOT roadside ditch?
Not by default; TxDOT reviews whether the site historically drained there and may deny new discharge.
Why would a pumped detention pond be denied?
Some cities limit pump locations or require gravity capability, and drain-time rules still apply.
What is a roadway impact fee?
A local fee under Texas Local Government Code Chapter 395 to fund roadway capacity for new development.
Why do restaurants pay higher roadway impact fees?
Fees are usually based on trips or vehicle-miles, and drive-thru uses generate more trips.
When should outfall access be checked?
During due diligence, before closing on the land.
Does JRH Engineering obtain building permits?
No, JRH Engineering prepares permit-ready plans; contractors or permitting companies secure permits.
